There are other methods than RAG over vector database; you can use basic TF-IDF or even full-text search to find candidate paragraphs and put them into the context.

Of course. “Retrieval” in RAG doesn’t require a special kind of retriever. As long as the relevance is tuned for the top documents to seed the prompt context, it doesn’t matter what kind of search backend you use.

  Agreed though R in RAG typically means specifically vector search. Not sure how this was called before vector DBs were popularized by LLaMAIndex, probably just retrieval systems with LLMs.

    That's not true. Information Retrieval needs much more than vector search. I've contributed to a book on the subject: https://aipoweredsearch.com https://aipoweredsearch.com

      Any more info? The book's not published yet, I see.
